DAE_SHAREDSN

Description:

Checks that in a sysplex environment DAE data set is shared between systems (DAE option SHARE(DSN) is in effect).

This check is only applicable for a system in a Parallel Sysplex® environment. Note, however, that this check is not applicable and will not run on a geographically dispersed Parallel Sysplex (GDPS®) controlling system (K-sys) in a GDPS environment.

Reason for check:

In a Parallel Sysplex environment, if the DAE data set is not being shared, it is possible that the system requests a dump for a problem occurred on another system in the sysplex. To prevent duplicate dumps on all systems in the Sysplex, IBM® recommends that you share the same ADYSETxx parameter values in each system.

This check will detect if the DAE data set is being shared in a Parallel Sysplex environment.

z/OS® releases the check applies to:

z/OS V1R11 and later.
